The problem of kids working in dangerous slaughterhouses continues to be a concern as the Labor Department announced its third agreement this week with a company in the industry agreeing to pay a penalty and reform its practices to help ensure it won’t hire underage workers again.

Agribusiness giants Purdue Farms and JBS Foods, along with a slaughterhouse cleaning company, paid about $8.4 millions in fines for having underaged workers in dangerous jobs.
